The present invention relates to the improved and efficient process for the synthesis of antiepileptic drug Lacosamide in high enantiopurity (>98% ee) and better yield. More particularly, the present invention relates to improved and efficient, cost effective process for synthesis of desired (R) isomer of Lacosamide starting from commercially available (S)-benzyl glycidyl ether.
The present invention relates to an improved process for the synthesis of (R)-Lacosamide in which free base of O-methyl-N-benzyl-D-Serinamide is not isolated before acylation. The process avoids the use of column chromatography and chiral resolution for the preparation of different stages of Lacosamide.
An efficient asymmetric synthesis of the new antiepileptic drug, Lacosamide is described in high enantiopurity (>98% ee), using Jacobsen's hydrolytic kinetic resolution strategy as a key step. (C) 2011 Elsevier Ltd. All rights reserved.
